Spatial Portfolio

Introduction

Your portfolio should demonstrate each of the following skills:

  • Displaying multiple vector layers on the same map
  • Calculating and displaying relationships among point and polygon layers based on distance
  • Aggregating point data to a layer of polygons
  • Calculating and displaying accessibility, based on travel time
  • Converting between raster layers and vector layers
  • Displaying raster data on a map
  • Georeferencing a raster image
  • Displaying data on an interactive map

Cambridge, MA

This map of Cambridge, MA visualizes multiple vector layers: open space and schools in the town.

Mumbai, India

For an assignment on Georeferencing, a map of Mumbai from 1960 was brought into conversation with both historical and more recent data about the city.

Philadelphia, PA

Portland, OR

This series of maps explores food access in Portland, Oregon. It uses transit data, grocery store data points, and poverty status to identify the neighborhoods in Portland with the most need for greater grocery store access.

Grocery Store Transit Accessibility

Grocery Store Walking Accessibility

The following two maps (the first a vector, the second a raster) visualize the same Walking Accessibility Scores. Very few neighborhoods in Portland are accessible on foot to grocery stores.
